Rails/RSpec/Capybara: Test raises "Missing template errors/internal_server_error}

[Josua Muheim]

The CSV export is working nicely, but when trying to test it, I get the following error:

Error during failsafe response: Missing template errors/internal_server_error with {:locale=>[:en], :formats=>[:csv], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :slim, :jbuilder, :coffee, :haml]}.

The spec looks like this:

require 'rails_helper'

describe 'Exporting findings' do
  it 'exports findings to CSV' do
    @project = create :project

    visit project_path(@project)
    click_link 'Export to CSV'

    # Error raised!
  end
end

FindingsController:

class FindingsController < InheritedResources::Base
  load_and_authorize_resource
  belongs_to :project
  respond_to :csv
end

Interestingly, the spec passes anyway:

I am sorry, but I cannot see how comma gem is related to this problem. So, I am closing this issue. If comma gem is related, please re-open this issue and explain how comma gem is used. Thank you.
